Clinical Application
Acute inflammatory response causes rapid decrease in zinc concentration. Consider appropriateness of request if CRP is significantly elevated (e.g. if CRP 100-200 mg/L, there may be a 40-60% decrease in serum zinc concentration).
Zinc results should be interpreted alongside albumin and CRP results.
